Im not even sure what you are trying to get at. Do you not believe we should observe the Lords Supper, we should only observe once a year or what?
Why the second; of course!
Just like it ALWAYS was!
I'd think that this would appeal to you as well; considering how that you are seemingly a bit paranoid about Christian 'rituals' that are NOT in Scripture.
"As oft as ye do it..." indicates ONCE a year to me!
